Does anyone see a problem with this....I'm testing next weekend.
seems a but complicated, are you using standard removable 25ltr tanks, the sort you can take out to re-fill? thought just a standard fuel line with primer would have been fine, just cut it before the engine to fit the separator, less to go wrong

My rib originally had one 25ltr removable fuel tank located in the console, a primer bulb located to the stern, then the quick release connection into the outboard.

The original tank is a pain in the arse to get to, ok if your moored up in a marina- but horrible to re fill out in the sea.!!

So I decided to install another 25ltr removable fuel tank to the stern. This also comes with its own primer bulb.

I also installed a water separator, fixed on the transom. The inlet side of the separator has a quick release connector. That way, I can swop fuel tank hose's quickly. Both fuel lines have their own primer and quick release connector.!

The outlet side of the water separator just has a short length of 3/8" hose(400mm) going to the outboard.

This is how I was advised to do it.....

Do you think ANOTHER bulb is required from separator to outboard.?

This would make 3 in total.!! Don't want too many parts if not needed..!

Thanks for any info

yes, makes perfect sense to me, must be coz I'm a bit thick only being a spark n all

anyway, yes, I see what you're getting at now, I think you may have been better off with just the one primer bulb between the separator and the engine, so you would suck the fuel through the separator rather than pushing it through, but in reality don't suppose it makes that much difference. I guess if you've got quick release fittings on both ends of each line it gives you the chance to swap lines if you have a problem when out on the water.

I suppose it wasn't clear that I have two independent fuel lines connected to separate fuel tanks.

I like this, as it means I can monitor my fuel.

I've had it tested on muffs, seems to work fine, I just didn't want any type of fuel starvation at WOT.

Not that it matters too much with my fuel injected 4st, it'll just run rough, rather than overheat from running too lean on the older 2st's..?

Thanks Chris
